Newsflash: [OR] – Will adding door to backyard increase value?

Howdy,I live in a two-story house that’s only door to the backyard is via our (unfinished) walkout basement. Would adding a door to the house (in the finished living space) with a staircase down to the yard increase our appraised value, or is it just a nice-to-have if we ever sell? Thanks for any insight as I try to prioritize a laundry list of project ideas!
